do celestial skills work on curses?

I have started a character with pets and picked up shepherds call. Because I don’t have any direct attack skills, I bound it to curse of frailty, but it doesn’t appear to trigger, at least not visibly.
If not on this one, might it work with grasping vines?
I thought it would trigger on attacks by my pets, but perhaps I am wrong?

I have several chars using some devotion proc linked to curse of frailty and it works fine. May your case be a bug?

visibly, you only have the constellation icon in the active skills bar, and you need to hover over it and read what it says to identify the constellation proc.

Having said that: This build http://www.grimdawn.com/forums/showpost.php?p=452586&postcount=1 binds dryad’s blessing to curse of frailty, and it does trigger.

They are (both) works.
I made some screenshot to show you how it works.
After crook triggering around the character start to rotate two runic symbol, and in the left pane (where displays all buffs) appears icon of devotion (star).

Thanks guys, I did see that star icon occasionally, but didn’t knew what to make of it. I’ll keep an eye out for the runic symbols which I didn’t see so far, probably for to much stuff going on onscreen.
